ROTARY VALVE.

Application iiled July 8,

My invention relates to rotary valves, particularly adapted for use inconnection with bath and sink coelrs, and has for its objects to providea construction wherein the valve will be opened fully by a very slightmovement of the handle, and will be of such construction that allwater-hammering in t ie pipes will be avoided.

.lhese objects I accomplish in the manner and by the means hereinafterdescribed and claimed, reference being had to the accom- 1 anyingdrawing, in which Figure 1 is a perspective view oit my improved valveshown applied to one of the pipes oi a combined hot and cold waterfaucet.

Figure 2 is a vertical longitudinal sectional view taken through thesame.

Figure 3 is a transverse sectional view taken on the line lll-IH ofFigure 2.

Figure Il. is a similar view taken on the line lVlV of Figure 2.

Figure 5 is a view partly in elevation and partly in section of thevalve construction.

Figure G is a view similar to Figure 5 showing the parts in section in adifferent position.

Similar numerals of reference denote corresponding parts in the severalviews.

In the said drawing the reference numeral l denotes the valve body l,the same being formed with a stem 2 at its outer end to receive a nut 3,whereby to clamp the same in position in a wall or partition, shown indotted outline in Figure 2. Screwthreaded onto said valve body is adelivery pipe l leading to the faucet, said pipe being provided With adiagonal slot 5 adapted to receive the operating handle 6 of the valve.A collar 7 carried by said handle is mounted rotatably upon the pipe 4,the saine being of a width to conceal the slot 5 in any position ofadjustment of said handle. The inner end of said handle isscrew-threaded to engage a similar screw thread on the inner end of thevalve body l, whereby any rotary movement imparted to said sleeve 9 willcause it to shift 1925. serial No. 42,167.

longitudinally upon said valve body 1. Formed integral with said sleeve9 is a spider 1G having a central screw-threaded aperture adapted toreceive a screw ll for attaching to the. said spider a valve disk i2,which may be formed of any suitable material. Said valve disk cooperateswith the formed by the inner end of the body l so as to close the sameagainst the iioiv of Water therethrough when the sleeve 9 has beenshifted to its extreme movement to the left. ln order to preventleakage, packing rings 13 and lil are provided between the sleeve 9 andpipe 41, and between said sleeve and the body l, as shown..

In operation a movement of the handle S in one direction will, throughthe engagement oi"- the cooperating screw threads on sleeve 9 and bodyl, cause the valve disk l2 carried by said sleeve to move to the right.to the open position shown in Figure 2, while a corresponding movementoi said handle in the opposite direction will cause a reverse movementof the sleeve 9, bringing the valve to the closed position shown inFigure 5. rlhe object of the diagonal slot 5 in the pipe 4: is toprovide that the handle 6 may be moved in accordance with thelongitudinal movement imparted to the sleeve 9 by its screw-threadedengagenent with the body l.

Through my improved construction a 'very slight movement ot the handle 6will shift the valve from closed to completely open position, and viceversa, and the construction is such that when opened there is a ree'ilowof water through the same, thereby preventing any hammering in thepipes.

Having thus fully described my invention, what l claim as new and desireto secure by Letters Patent, is

l. A rotary valve, embodying a valve body, a sleeve on said body and inscrewthreaded engagement therewith, a valve carried by said sleeve andmovable by the rotation ot' said sleeve into and out of contact with oneend of said valve body to open and close a -central passage through saidvalve body, a pipe engaging said valve body and enclosing said. sleeye,and a heL (lle for operating said sleeve projecting through au inclosedSlot in Said pipe.

2. A rotary ,f'alve, embodying 2L valve hotly, e sleeve on said hotlyand in screwthreeided engagement therewith, a spider ai, one end ol aiosleeve.l e valve disk cer ied by Said spider und adapted to engage oneend 01"' said valve body to close a central aperture therethrough, apipe engaging seid Valve body and enclosing said sleeve, and u handlefor operating' projecting through :in inclosed Slot in said pipe.

ln t Jtimony whereof I hereunto aliix m y signature.
